Question

define limiting friction

Answer 1

Limiting friction is the maximum value of static friction that comes into play when a body is just at the point of sliding over the surface of another body.

Answer 2

Explanation:

Limiting friction:

When two static surface comes to contact to each other then the friction generate. This friction is called limiting friction.

When the object is on the point of sliding then the limiting friction generate.

The limiting friction is the product of the normal force and coefficient of limiting friction.

$F=\mu N$

Here, $\mu$ =coefficient of limiting friction

N = normal force

The limiting friction force is always opposite of the motion of the object.
